Passwords: What if Everything You Know Is Wrong?
Posted in: Uncategorized
Every time there’s a notable cybersecurity breach, someone (even me) writes a comprehensive primer on the proper way to create “secure” passwords. Lather, rinse, repeat. Until a few years ago, everyone (including me) based their password advice on a 2003 paper from the National Institute of Standards and Technology (NIST), with the catchy title “NIST Special Publication 800-63.” The paper recommended that passwords be cryptic, contain special characters, and be as close to nonsense as possible.
I was in a camp I called “How to Make a Cryptic Password You Can Easily Remember.” The short version was this: Take a phrase you know, such as a favorite quote from a movie, and use the first letter of each word. For example, Sheriff Brody’s famous line from Jaws, “I think we’re gonna need a bigger boat,” becomes 1twgn@bb. The trick was using Leet (a technique where letters are replaced by numbers and symbols; see my post from July 2012, “Yahoo! Hacked: What You Need To Do Now”) to add the numbers and special characters. But as you can see from the example, a password made in this way is total nonsense to everyone but you — unless you forget your favorite quote.
That was then
